It took me a while but i was able to perform tests that add up to 600 rows in the database per second. This is quite good in opposite to the 200 i was able to do before. I changed my application to use JDOM for transforming the POJO's into XML that's returned to the clients. Before i was using the default JDK's JAXP/TRAX stuff. I also made some significant changes to my test client application. I changed some settings on the client machines as explained user http://grinder.sourceforge.net/faq.html#windows-address-in-use. Futhermore the clients are using buffers to read the response which is much faster (shame on me, i know). That sounds good but of course there are still a few problems.
After starting JBoss i perform a test with 250 virtual users, each user performs 12 requests per minute, so an average load of 50 requests per second is placed on the server and this during 5 minutes. This test always fails. After about 4 minutes it is as if the server blocks for a while and connections start to time out while other requests have a response time of more than a minute. When i repeat this test (without restarting JBoss) and during the following tests, with a higher number of users, all goes fine. It is as if the server needs to warm up before it can handle a higher load. This happens every time after restarting JBoss. The same happens with my test with 2300 virtual users. After this test i can continue testing until 3000 virtual users (about 600 requests per second) after which the limit seems to be reached. Somebody any idea of what's happening?
